Photoreceptor charging systems and methods

A method comprising:

• patterning a charge on a document zone of a photoreceptor;
• attaching toner to charge patterned regions of said photoreceptor;
• charging said document zone of said photoreceptor with a first voltage;
• charging an inter-document zone of a photoreceptor with a second voltage that is larger than said first voltage;
• and
• transferring said toner from said photoreceptor to a printing medium, wherein said second voltage reduces an amount of charges trapped within layers of said inter-document zone of said photoreceptor;
• and
• increasing a size of said document zone from a smaller size associated with a smaller printing medium to a larger size associated with a larger printing medium, wherein by reducing said charges from being trapped within layers of said inter-document zone of said photoreceptor, ghosting is reduced on said larger printing medium.

A method comprising:

• patterning a positive charge on a document zone of a photoreceptor
• attaching toner to positively charged regions of said photoreceptor;
• charging a said document zone of a said photoreceptor with a first negative voltage;
• charging an inter-document zone of a photoreceptor with a second negative voltage that is more negative than said first negative voltage;
• and
• transferring said toner from said photoreceptor to a printing medium by applying a first transfer current to said printing medium and applying a second transfer current lower than said first transfer current to said inter-document zone of said photoreceptor.

An apparatus comprising:

• a photoreceptor;
• an exposure device adjacent said photoreceptor, wherein said exposure device is adapted to pattern a charge on said document zone of said photoreceptor;
• a development station adjacent said photoreceptor, wherein said development station is adapted to attach toner to charge patterned regions of said photoreceptor;
• and
• a charging station adjacent said photoreceptor, wherein said charging station is adapted to charge a document zone of a photoreceptor with a first voltage having a first polarity and to charge an inter-document zone of a photoreceptor with a second voltage having said first polarity that is more biased toward said first polarity than said first voltage;
• and
• a transfer station adjacent said photoreceptor, wherein said transfer station is adapted to transfer said toner from said photoreceptor to a printing medium.

• and
• a transfer station adjacent said photoreceptor, wherein said transfer station is adapted to transfer said toner from said photoreceptor to a printing medium,
• wherein said second voltage reduces an amount of charges trapped within layers of said inter-document zone of said photoreceptor, and
